Anyone here with labor law knowledge

I realize this is Wayyyy off topic, but seen other similar posts, so what the heck.

Not sure if that applies here, but closest to what information I am looking for, Here's the story.

Two weeks after applying for a job at a place, where i work through a temp service, I got an interview for Sunday March the 20th. Not sure why they do this on weekends, they just do. anyways i was told the following Thursday, they would look over all applicants and decide, who to hire. I recieved their little card that means "thanks but no thanks" on Friday after the deciding day, the next day after the deciding day. What bugs me is, this is the second time i had an interview (first in 2009) and asked then why i was passed over. I was told they couldn't discuss it, Why is that? They don't want to hurt feelings? confidential? I'll grant i am a big guy (over 300#) and may not be one of the fastest guys on the floor( this is a warehouse job, Loading and unloading trucks), but i have nearly three years through the temp service. Shouldn't that count over someone just walking in? Sorry for the rant, the bad typing and the long post, but i have a question.

Does a perspective Job have to tell you why they did not hire you if you ask? I would think, i'd be better prepared next time, if i knew what blew it for me. Links if found would be helpful in my quest, Thank you
